The family of an 11-year-old Navajo girl who was kidnapped and killed last week has raised concerns about unauthorized fundraising accounts online.

The concerns led the Navajo Nation's San Juan Chapter to pass a resolution Tuesday calling for halting fraudulent and unauthorized fundraising.

Ashlynne Mike was found dead May 3. Authorities said a stranger lured her into his van the day before.

Chapter president Rick Nez said Ashlynne's father, Gary Mike, will hold a press conference at 7 p.m. Thursday at the San Juan Chapter House east of Shiprock, in part to thank the community and others for their support in the wake of his daughter's death.

About $11,000 raised to support the family has been placed in a Wells Fargo account that the Mikes set up after last week's death.
